Basic process prototype

Make an initial workflow for contributions, including
things like frequency.

Make the "contribute more than once" checkbox have some
different text when it's not selected, and other
UX refinements to make the proto design not too bad
for the time being.
Sum the one-time price and recurring price

There are two types of contributions: one-time
and recurring each month. Calculate and show
what each of these are, as things are selected.
Show hearts and copper hearts when things selected

... in the 'total' column. For fun.
